WILLIAM C. BULL, OF LOS ANGELES, CALIFORNIA.

LISTING, COUNTING, AND PRINTING, MACHINE.

Application filed January 27, 1926.: Serial No. 84,040.

This invention relates to a listing, counting and printing machine for making up a list of articles, counting each article, and printing the list and the result of the count of each article.

An important object of my invention is to provide a machine of the character stated which may be used by laundries for makmg up lists of clothes and otherarticles to be laundered, counting each of the articles 111 the list and printing the list together with the laundry price and the result of count of each article opposite the same. 7

It is at present the practice'of laundries to print on sheets of paper a list of'every kind of article that may be laundered, together with the laundry price of each an ticle opposite the same; and when it is de sired to list a bundle of laundry, a check mark is made on one of said printed sheets on the name of each article thereon, corresponding to a like article or articles in said bundle, and the number of each of the articles in the bundle is written on said sheet opposite the name of said article which has been'checked on the sheet.

The disadvantage of this practice is that the articles checked on the sheet may be scattered, that is to say, one article may be checked at the top of the sheet, another at the bottom and another half way between the top and bottom of the sheet, which makes the laundry list hard to read, and makes it difficult to add up the number of articles checked and the total laundry price thereof.

It is another object of my invention to print the list of articles, with their laundry prices and the numbers thereof, CODSGCU. ti'vely together so that the list may be more easily read and checked and the total laundry price thereof more easilyadded up, thus effecting a considerable saving of time and labor in checking and bookkeeping and making itpossible' for the operative in the distributing room to determine readily how large a space to reserve forthe laundry bundle.

Another object is to provide a machine of the character stated which will be fool proof. that 'is to say, it will prevent mistakesv in listing. because it will print only the names of those articles handled which are contained in a bundle. i

The invention has for a further object the provision of improvementsof the general character stated, which will be generally superior-in point of relative simplicity and inexpensiveness of construction, taken in connection with positiveness and reliability in action and performance, and convenience in handling 'a-ndmanipulation, and which will be generally superior in efli ciency and serviceability. I

'With the above and other objects in View, the invention consistsin the novel and useful provision, formation, construction, com.- bination, association and relative. arrangement ofparts, members and features, all as hereinafter described, shown in the drawing, and .linally pointedv out in claims.

Fig. 10 is a face view of a laundry list made up and printed 011 my machine.

Corresponding partsin all the figures are designated by the same reference characters.

Referring with particularity to the draw- Fig. 5 is a front end view of the invenings my invention comprises generally a printing cylinder A, a printing carriage B, a

plurality of printing units G mounted in said carriage, and an inking device D, all of which elementsare mounted on a box-shaped base member E. I

The printing cylinder A is secured on a shaft 1 which is journaled at its ends in the side walls 6 of the base member E as at 2 so the cylinder is journaled transversely the cylinder, there being springs 6 connected at one end to said arms at 7 andat their otherends to the ends of the cylinder at 8 for normally holding the clamp a in damp ing position'with its her 5 against the forward portion of a list sheet L which is placed on the cylinder whereby said sheet is clamped on the cylinder by said clamp asshown in Fig. 6. The name and address of the laundry may be previously printed on the list sheet. A guide roller a engages and holds the rear portion of the sheet L on the cylinder A, which roller is journaled in a swing frame a, comprising a pair of arms 9 and a connecting member 10 connecting the lower ends of said arms, the arms being fulcrumed on pivots 11 secured in the side wall 0 of the base member E and the guide roller a being journaled in the outer ends of said arms, there'being springs 12 connected at one end to the frame bar 10 at 13 and at their other ends to the side walls 6 of the base member E, which springs hold the frame with the roller a in engagement with the list sheet L, as shown in Fig. 7 in dotted lines. On the swing frame arms 9 are projections lt for engaging the clamp arms 3 and swinging the clamp a out of engagement with the list sheet L, when the swing frame a is swung on its fulcrum against thetension of its springs 12, and the roller a released from thesheet, thus releasing the sheet so that it may be removed from the cylinder. On the cylinder shaft 1 between one end of the cylinder A and the-adjacent side wall e'is secured a gear 15 provided with a notch 16 in its periphery to receive a latch 17 which is pivoted at 18 to the inside of one of the side walls 6 whereby the cylinder and the list sheet clamped thereon are locked intheir initial printing position as shown in Figs. 1 and 8.

The printing carriage B includes a boxshape'd casing 20 open at the bottom and mounted at its sides on channel-shaped slides 21 which slide on tracl s 22 secured on the upper edges of the side walls 6 of the base member E whereby the printing carriage B is mounted to slide on the base member over the printing cylinder A. The upper. wall of the casing 20 is provided with a plurality of transverse slots 23. Transversely inclined bars 24 and 25, shafts 26 and 27, rods 28,29,

30, 31, 32 and 33 and a guide member 34 extend longitudinally within the casing 20, said bars, rods and guide member being secured at their ends to the end walls of said casing,

while the ends of said shafts extend through said end walls and are jour'naled therein. To the upper wall of the casing 20 within the casing is secured a vertically depending guide plate 35 provided with vertical 'slots36 of said ratchet, a concentric locking rack cut in the ratchet wheel J, a spring, dog 7 mounted in the sleeve 37 for engaging said rack, a detent m fulcrumed on the shaft 27 and a pull rod a connected to said detent. The type bar F is provided with an inclined slot 7" through which extends the inclined bar 241:, and the upper edge 7' of said type bar is inclined parallel to the under side of bar 25 for engagement therewith. The type bar F is provided with a notch f in its upper edge near its outer end to receive the lower end of the actuating lever H. A part 7 of the lower edge. of the type bar F at the outer endof the bar is adapted to engage the teeth of the. cylinder gear 15. T ie type wheelG is'turnably mounted on the stationary sleeve 37. Theupper end of the lever H'extends through a slot 23 in the uper wall of the carriage casing 20. The levers H of adjacent units C aroof different lengths so that the upper end of; any lever may be readily grasped without grasping at the same time another adjacent lever, thus preventing inaccuracies in printing by setting the wrong type. The upper portion of the lever H is connected to one end of a spring 39 which connected at its other end to the rod 29,

which spring resists outward movement of the lever. The pawl j is connected to the upper end of a. spring 40 which is connected at its lower end to the'rod' 30, said spring normally holding the pawl is engagement with the teeth of the ratchet- J The lower edge of the pawl j rests upon'the rod 32 which serves as a guide for lifting the engaging end of the pawl out of engagement with the. teeth of the atch'et y" into a slot 36 when the lever H is swung toits extreme'in ward position, in which slot the pawl is held in alignmentfor swinging down into enlln i 20, between the end walls of said casing gagement with the ratchet when the lever H is swung outwardly. The pull'rod it extends through anopening nin the top wall of casing 20, and-through the guide34, and is connected at its lower end'to the detent m. The push rod is also connected to the upper. end of a spring 41, the lower end or which isconnected to the rod 31, which spring resist's upward movement of thepush rod.

' On the type Wheel G is provided a lug-g which projects beyond the periphery-of the wheel-and is arranged to engage the rod 83 to arrest the return movement of the'type wheel in zero position. I

"A return actuator K is provided for re turning the type wheels G of all of the'prin'tingainits C to, zero position. when said wheels have printed their selected members on alist sheet, which actuator comprises a pair of 'arms'kand a bar is connecting the outer ends of said arms and extending across the peripheries of the'type wheels of all of said units, the inner ends of said arms being secured on the shaft 26 within the casingl anc the ends of the sleeve 37 (see Fig. 4t). To one of the arms is of the return actuator K is connected one e'ndof a link 42, the other end of which is connected to one arm of one of a pair of bell .cranks fulcrumed on the shaft 27. Thcother arms of said bell cranks are connectedto a bar for engaging the lower edge of the detents m for the purpose hereinafter'more fully set forth. On the I front end of the shaft 26 outside the casing is secured a crank P.

On the top wall of the carriage casing 20 adjacent the slots 13 respectively are placed the names of the various articles that may be printed by the machine on the list sheet, such as Shirts, Collars,Handkerchiefs, etc. to indicate which levers H should be pulled to count the numbers of the different articles to be listed and to setthe number wheelsG to print'said numbers. v

The inking device Dcomprises a frame 43, secured to the inside of the sidewalls e of the base member E, an ink roller cl journaled in the upper part of said frame trans versely of said base member in position to ink the set type bars F and type wheels Gr when the carriage passes over said roller, and an ink pad d mounted in said frame for wiping said ink roller and applying ink thereto. The operation of my invention is as follows: e The printing carriage B is at first at the left end of the base member E as shown in Figs. 1 and 6. The cylinder A is held in position to receive a list sheet L, by the engagement of the latch 17 with the, notch 16 in the gear 15. I A list sheet is inserted under the guide roller a andthe clamp a on top of the cylinder A and clamped by said clamp article'such as a shirt is picked up, the lever ll'findicatedShirts, is pulled forwardly intothe position shown'in dotted lines in Fig; 3, whereuponithe lower'end of said lever enforces the typ'e bar F rearwardly, while the pawl'j is drawn forwardlyout of the guide plate iiito'engagement with a tooth of the ratchet -J, whereby the type wheel G is advanced one'unit or from zero to'l with the type 9 of said wheel bearing the numeral 1- in its lowermost and printin position in whichposition the wheel is'hel d'by the dog and rack The rearward movement of the type bar F brings the'inclined bar 24 into engagement with the sides of the'slot and the inclined bar 25 into engagement with the upper edge of the type bar, where by. the" type bar bearing the type f with thewvord Shirts 18 caused to be lowered so that saidftype' will be in printing position. l Vhe'n the le'v'er-H'ispulled forwardlyns above describedthe detent m is forced downwardly by the pull rod 9% under the influence of thespring 41, so as'to engagethe rear edge of the lever H to limit the return movement of said lever under the influence of its spring 39 and 'preVent 'th e lever from withdrawing the type'bar F from printing positiorn but at thesame'tiine allow sufficient forward movement of the lever to e11- able the pawl to advancethe ratchet J one tooth and the type'wheel G one unit each time such movement of the lever is effected, as illustratedi'n Fig. 3. If another shirt is gagesthe rear edge of the notch f and l (it) picked up from the bundle, the lever H will be pulled forwardly from its dog-locked position, shown. in full'lines in Fig. 3, to its dotted line position, shown in said; figure, whereupon the pawl j will advance the ratchet- J'one tooth and the'type wheel (Jr one unit, in which position of the type wheel the type 9 bearing the numeralQ will be in. its lowermost and printing-position. For each additional shirt found in the bundle the last described operation ofthe lever will be repeated, so that lowermost type 9 of the wheel G will bear the number correspond ing to the number of shirts in the bundle.

VVhenother articles such as collars, handkerchiefs, etc. arefound in the bundle the lovers H corresponding to said articles, will be opeate'd' to set the type bars F and type wheelsG to print'the name and n'umberof such articles, in the same mannerthat the lever H corresponding to shirts was operated print the name and number of shirts found in the bundle as above described.

, WVhen all of the type bars and type wheels are set for printing the names and numbers of the different articles, the carriage B is moved onits tracks 22 to the rightfirst over the inking device D and then over the cylinder A. As the carriagevis moved over the inking device, the type f and g on the type bars F and G which are set for printing, are inked by the inking roller d. p

. As the foremost unit C, whose type bar and type wheel are set for printing, is moved over the cylinder A and the name and numher of an article printed by said unit on the list sheet L on said cylinder, the edge f of the type bar F of said unit will engage a tooth or gear 15 (see Fig. 9) and r0- tate the cylinder A. a short distance equal to the predetermined space between two adjacent items on the list sheet L, so that the next unit C may print the name and number of its article directly under the name and number of the article printed by said first unit. the latch 17 being lifted by hand out of the notch 16 to permit such rotation of the cylinder. The carriage being moved further to the right, the second unit C will print the, name and number of its article directly under the name and number of the article printed by the first unit, while the edge f of said second unit will engage a tooth of gear 15 and rotate the cylinder a. short distance so that the third unit 0 may print the name and number of its article directly under the name and number of the second unit. The above described operations will be repeated upon further movement of the carriage B to the right until every unit C, set for printing, has passed over the cylinder and the name and number of every article in the bundle will be printed one immediately under the other on the list sheet L.

When the list, including the name, number and laundry price of each article is printed on the listsheet L, the crank P is rotated counter-clockwise which correspondingly rotates the shaft 26 and return actuator K, and through the medium of link 42, the bell cranks O on shaft 27 are correspondingly swung, whereupon the bar K of the return actuator engages the lugs g of the type wheels G, of all the printing units O which have printed their items on the list sheet L,

till

and rotates said wheels counter-clockwise until arrested in their zero position by the engagement of said lugs with the rod 33, while the bar 0 of said bell cranks engages the lower edges of the detents m and lift the detents out of limiting relation to the levers H, whereupon the springs 39 of the rearward and swung upwardly by their engagement with red 32 into slots 36 in guide plate 35, while the lower ends'ofsaid levers engage the forward edges ofthe notches f of the type bars F of the units which l1ave printed their items and withdraw the type bars forwardly and upwardly out of print- .ing position. The crank P is then swung, clockwise back into its initial position and the printing carriage B is. moved on its tracks 22 back to the left or front end of the base member E. The cylinder A is rotated by hand counter-clockwise until the latch 17 engagestlic notch16 in gear. 15 and arrests the cylinder inits initial printing'position. The swing frame a is swung coiinter clockwise and guide roller a lifted out of engage ment with list sheet L, while the projection 14 engages an arm 3 of clamp a and swings said clamp out of engagement with said sheet. The printed list sheet isfthen removed from the cylinder. i

Any individual detent on may be lifted out of limiting relation with alever H by pulling up the pull rod 92 connected to the detent, so that the lever may be swung by its spring 39 back into its initialposition and the lower end of the lever caused toengage and withdraw the type bar F from printing position. v Referring to Fig. 10 it will be seen that my machine prints the name, number and" price of each item immediately adjacent the name, number and price of anotheritem so 1 that all of the items are grouped close together and not scattered apart as in the present practice of listing. I

With the items listed close together by my machine they may be more easily read and their numbers and prices more easily added than is possible when the items are scattered, thus effecting a considerable saving of time and labor in checking and bookkeeping and making it possible for the operative in the dis tributing room to determine readily how large a space to reserve for, the laundry bundle. I l

It is obvious that many changes and variations may be made in the general and particular construction of the device audits parts and features, in relation to the recitals hereinabovemade in that regard, in practicing the invention, and in adapting it to varying conditions of use and service, without departing fromthe true spirit "of the invention.
